6,465, and in Cuba August 3, 1924 Renewed This invention relates to a safety stopper 11, present flanges 12 and 13 for snapping and to a container with which the stopper is over flanges 7 and 9 in the extension land used, whereby, after having once extracted the original contents from the container, the same cannot be subsequently refilled in its original form. It is applicable to all forms and sizes of containers and insures the origi. of the contents.

A further object is to simplify the construction of devices of this character, reduce the cost of their manufacture, and increase their eficiency.

One physical embodiment of the invention is shown, by way of example, in the accompanying drawings, wherein;

Fig. 2 is a section on line22 of Fig; 3;

Fig. 3 is a section on line 33 of Fig. 2;

Fig. 4 is a plan view of a detail; and

Fig. 5 is an elevational view of the detail of Fig. 4.

As shown in the drawing, a container 1, of any desired size and form, has a neck 2 receiving a stopper 3. The neck 2 has an exand an inner diamond cut 5, whereby to lacilitate breaking the extension 4t oil of the neck 2, by means of a blow on neck 6 carried by the extension. On the rim of the extension 4 is formed an internal undercut flange 7.

p A cap 8, as shown in Fig. 2, is formed to it closelyover the rim of extension 1 and carries an internal undercut flange 9, similar to flange 7.

A segmental stopper is provided, formed of segmental pieces 10, of glass or other-ma terial, fitting over a resilient plug 11 as oi rubberor cork, as shown in Figs. 4 and 5. The pieces 10, when in position around the plug Fig. 1 is a view of the device, in elevation tension 4, at the base of which is a groove 5' cap 8, respectively.

Operation of the device is as follows Container 1 is filled with-its contents, and

stopper 8 isinserted.

flange 9. Cap 8 is then pushe (1 over the rim of extension 1 until the stopper flange 12 is forced past inclines 7 and snaps under the extension flange 7. Thus, as sh own in F ig. 2,

container 1 is securely sealed, and can only be unsealed by breaking off extension: 4 along groove 5 and diamond cut 5. Refilling of the container in its original form is thus made impossible.

Advertising matter 0 can be carried by the outerpo sion 4:, if desired.

'Having described one tion, I now claim;

f vario us description, rtion of exteni'orm, of my inven- In a device of the character descrlbeiha contamer, a neck on the container, a plug in the neck, an extension on the neck projectingbe-;

yond the plug, an internal, undercut flange at the outer end of the extension, a cap for fitting over the end of the extension, an internal undercut flange in the cap, a

In testimony whereof I have signed my name to this specification.
